COMBINATION HARROW, PULVERIZER, AND DRAG.

Specification of Letters Patent.

Patented Oct. 29, 1907.

Applieaticn filed April 23, 1907. Serial No. 369.849.

To all whom it may concern:

Be it known that I, ARTHUR D. ULERY, a citizen of the United States ofAmerica, residing at Scenery Hill, in the county of Washington and Stateof Pennsylvania, have invented certain new and useful Improvements in aCombination Harrow, Pulverizer, and Drag, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to a combination harrow, pulverizer and drag, andthe invention has for its object to provide a novel implement fortilling and treating soil, the implement accomplishing the work of threeimplements, thus reducing the labor and time ordinarily consumed inpreparing a piece of ground for seed.

Another object of this invention is to provide a simple and inexpensiveimplement of less draft than the ordinary harrow, the implementdisintegrating the soil as thoroughly as a harrow, and at the same timeleveling and filling up depressions of uneven plowed ground.

With the above and other objects in view, the invention consists in thenovel construction, combination and arrangement of parts to behereinafter more fully described and then specifically pointed out inReferring to the drawing forming part of this specification, likenumerals of reference designate corresponding parts throughout theseveral views, in which:

Figure 1 is a plan of my improved implement, and Fig. 2 is alongitudinal sectional view of the same.

To put my invention into practice, I construct my improved implement oftwo side frames 1 having forwardly extending beams 2. The forward endsof the beams 2 are provided with yokes 3, whereby chains 4 can beconnected to said beams in order that the implement can be moved overthe soil, either by a traction engine or horses. In the beams 2 arejournaled transverse tubular shafts 5 and 6, and upon the shaft 5 aredetachably mounted a plurality of sleeves 7, said sleeves being equallyspaced and provided with arms 8. Riveted or otherwise secured to thearms 8, as at 9, are blades 10 having curved cutting edges 11.

Upon the shaft 6 are mounted a plurality of sleeves 12 having cuttingblades 14, said blades being similar to the blades 10 with the exceptionthat their ends are curved, as at 15. The sleeves 12 are equally spacedupon the shaft 6 and arranged in staggered relation to the sleeves uponthe shaft 5, whereby the blades 14 will be staggered with relation tothe blades 10. The blades 14 have their edges curved inwardly towardsthe center of the implement, so that the soil agitated by said bladeswill be thrown upwardly and inwardly, whereby clods of earth will bemore finely disintegrated, than .if the ordinary straight blades wereused.

The inner sides of the frames 1 are provided with rails 16 and securedto the bottom of said rails and the bottom of the frames 1 is atransverse plate 17 having an upwardly bent forward edge 18. The plate17 serves functionally as a drag for pulverizing and leveling soil, andthis plate can be constructed of metal, or a plurality of planks can bearranged to serve functionally the same purpose. Centrally of the plate17 is arranged a drivers seat 19, while in front of the drivers seat areplaced two supports 20 for pivoted operating levers 21. The pivotedoperating levers 21. are connected by links 2 and 23 with the crank arms24 and 25 of the shafts 5 and 6. The operating levers 21. are providedwith a conventional form of locking pawl 26 adapted to en gage intoothed segments 27 carried by the supports 20. In this manner, theshafts 5 and.6 can be partly rotated by the operator of the implement,to raise and lower the blades 10 and 14.

In operation, the blades 10 and 14 can be positioned to treat the soilas desired, the depth of the blades within the soil being determined bythe operator of the implement. The straight blades 10 are adapted tosimply cut the clods and soil, While the blades 14 more finely dividethe soil when they are set at a medium depth, but when lowered, thecurved edges of the blades come into use, and in addition to finelycutting the soil, they turn the same and fill up depressions in thesoil. Following the blades 10 and 14 is 'the plate 17 or the drag, whichcompletes the operation of pulverizing and leveling the soil. p

It will be apparent from the illustration of my invention that I havedevised a strong and durable implement for agricultural purposes, theimplement serving functionally the same purposes as a harrow, pulverizerand drag, and while I have herein described the preferred construction,I desire it to be understood blades carried by said sleeves, the bladesof one shaft hav-- ing; curved edges, a plate arranged between saidframes, a seat carried by said plate, operating levers pivotally supported by said plate and connecting with said shafts, and means forlocking said blades in a raised or lowered po sition.

2. An implement of the type described consisting of beams, shaftsjournaled between said beams, a plurality of staggeredly arranged bladesdetachably supported by said shafts, some of said blades having curvededges, 2. plate located in the rear of said shafts, a seat carried bysaid plate, and operating levers arranged upon said plate for bladescarried by the Other shaft, certain of said blades 0 raising andlowering aid blad s, having curved edges, and means carried by the plateand 3. An agricultural implement of the character described connectedwith the blades for elevating and lowering them.
